Claims priority, application Germany June 4, 1957 The present inventionrelates to improvements in the setup of a plurality of spinningmachines.

The machine frames and cross connections of old-type spinning machineswere usually made of cast iron which meant a heavy load to be supportedby the floor. On the other hand, the stability of the machine was veryhigh, particularly if the machine had a low center of gravity. Theprogressive development of spinning machines led to a departure fromcast iron frames and to the introduction of machine frames whichsubstantially consist of commercial structural steel, or vertical rodsor tubes or of sheet metal sections and are connected by horizontalbraces. As long as such machines are made with 'a low center of gravity,the stability thereof will hardly be aiected. However, the narrower sucha machine is made or the more a single center element only, such as acolumn, is relied upon for supporting a twosided machine and all theaccessory parts thereof, the less will be its stability. In consequenceof such low stability, vibrations may occur within the machine whichwill have an ill eiect upon the actual operation thereof, aside from theelect which such vibration might have upon the machine parts which aresubjected to other vibrations even n the normal course of operations andwhich will thus withstand these stresses for a much shorter length oftime. Since el'rorts are constantly being made to design machines whichrequire the least possible space, the inevitable disadvantages of suchdesigns should also be kept in mind. a

It is the primary object of the present invention to provide a newmachine arrangement which will eliminate the above-mentioneddisadvantages and will also furnish certain new advantages not containedin the prior machine assemblies.

According to the present invention these objects will be attained byproviding the machines with elements which interconnect the machines andare disposed above the space required by the operators for servicing themachines, and which are also designed to support certain equipment orfixtures which are required for the operation of spinning machines.

The connecting elements according to the inventio are secured to theupper ends of the machine frames and preferably consist of connectingyokes extending from at least one machine to an adjacent machine. Theseconnecting yokes may be secured either to each machine frame, or toevery other machine frame in a staggered arrangement, or in any suitableorder of succession in a direction vertical or at an inclined angle tothe longitudinal axis of the machines.

The connecting yokes may be designed so as to support light fixtures, orto serve as a track for travelling bobbin frames, or as a track forcleaning or air-purifying means travelling above the machines.

"llhe present invention will now be described'in detail with referenceto the accompanying drawings, in which:

Figs. 6 and 7 respectively show diagrammatic side views of a portion ofa spinning machine provided with a running-off frame;

Figs. 8 to 10 respectively show additional basic setups for a pluralityof spinning machines arranged in a row; while Figs. 1l and l2 showfurther details of the invention.

Referring to the drawing, Fig. l illustrates several spinning machines 1of the same type which are substantially parallel to each other and areset up in a row. These machines are of a relatively small Width, asindicated in Fig. 2. The particular machines illustrated, for example,are double ring spinning machines, the stands 2 of which carry lasupport 3 and columns 4. The machines are equipped in the usual mannerwith spindles, a ring rail, thread guides, etc. The drawing frame 5 ofthe ring spinning machine, as shown at the left side of Fig. 2, isdisposed Within the central longitudinal plane of the machine and isadapted to receive the sliver to be drafted from bobbin 6 through guiderollers. The double ring spinning machine -as shown at the right side ofFig. 2, is equipped with drafting frames S and 5", respectively, foreach machine row, in order to illustrate that the arrangement accordingto the invention may also be used for machines of the type thus shown.Particularly whenever the machine stands 2 do not consist of a cast ironfname but are merely central supports erected on the oor, there existsthe danger that, owing to the high spindle speeds employed at thepresent time, the machines will tend to develop vibrations which willthen not only unfavorably affect the spinning process, but also the lifeof the machine parts. In order to avoid such disadvantages from thestart, according to the present invention, said supports 3 carry columns4 or the like which are interconnected by connecting yokes 7 forming labridge over the service aisle between each two adjacent machines.Connecting yokes 7 may be arranged in different ways, as shown, forexample in Figs. l, 3, and 4. According to Fig. 1, each first, third,iifth, and every other column of the rst machine is connected with therespective columns of the second machine by means of a connecting yoke7, while each second, fourth, sixth, and every other column of thesecond machine is connected with the respective column of the thirdmachine, while each first, third, iifth, and every other column of thismachine is, in turn, connected with the respective column of the fourthmachine, and so forth. As shown in Fig. 3, all the columns of eachmachine are connected with the respective columns of the adjacentmachines. Fig. 4 shows a further possibility of arranging the connectingyokes so as not to extend in a direction vertical to the longitudinalaxis of the machine, but lat an inclined angle to the latter, so that azig-zag connection of the adjacent machines is attained, as indicated bythe fully drawn-out lines. There is also the possibility of attaining acrosswise connection as shown in Fig. 4

. by the dotted lines. There are, of course, still other posin theprovision of means for mounting other equipment and fixtures, requiredfor a proper performance of the spinning operation.

Thus, for example, the inventionI permits a considerable improvement inthe illumination of the work rooms. If the light fixtures are mounted inthe usual manner at a considerable height above the machines, theresults will be an almost uniform distribution of light within the room.However, this will also require a relatively large number of lightfixtures or very strong light sources in order to obtain an adequateillumination at those points of the machines where such strong light isrequired for a proper operation. These points are primarily the drawingframes and thek spindles. Presently used light systems and most of thepresently used types of light fixtures are, however, incapable ofilluminating these particular spots sufficiently, particularly since thebobbin racks or creels of the machines interfere. The disadvantage maybe entirely and very simply eliminated by means of the presentinvention, as illustrated, for example, in Fig. 2. The connecting yoke 7is in this case designed in the form of an inverted U-shaped rail. Thechannel thus formed may receivev a lluorescent tube 8, the light ofwhich will then be directed almost exclusively toward those points ofthe machine which require good lighting, that is, particularly, thedrawing frame and the spindles. Because of the different manners inwhich the yokes 7 may be arranged between the individual machines, asshown, for example, in Figs. l, 3, and 4, it is also possible to providethe light fixtures in the most favorable positions.

Aside from being used for supporting the light iixtures 8, theconnecting yokes 7 may also be employed` as a support of the bobbincreel and in such a manner as to permit an easier handling thereof fromthe machine oor. Such an arrangement will be of particular advantage ifseveral rows of bobbins are arranged behind each other, because normallythe most rearward row of bobbins is especially hard to handle. Anexample of such an arrangement is shown in Figs. 5a and 5b. If theindividual machines are connected by connecting yokes 7 as shown in Fig.3, one supporting creel 9 for bobbins 6 may be attached between eachpair of adjacent connecting yokes 7. For this purpose, guide rollers 10are provided in pairs at both ends of creel 9 whichv may be moved backand forth along =a suitable surface of the connection yokes 7. In thismanner it is possible to slide a supporting creel 9 out of its operativeposition close to the drawing frame and in the longitudinal direction ofconnecting yokes 7 into the service corridor between the machines, sothat any operation required in connection with the manipulation of thebobbins 6 may be performed much easier than it would be possibleifbobbins 6 had to remain constantly in a once fixed position close todrawing frame 5, as it is the case with the heretofore known types ofbobbin creels. This new provision also does not result in anydisadvantages to the orderly travel of the individual slubbing strandssince the latter are guided to the drawing frame by means of guiderollers which are rigidly mounted on columns v4, no matter whethersupporting creel 9` is in its operative position close to the drawingvframe or in pulled-out position above the service aisle,

Instead of supporting creel 9 holding individual bobbins 6, it is alsopossible to arrange in a similar manner for the suspension of draw-oh?creels holding several yarn balls on a continuous sleeve located betweeneach pair of adjacent connecting yokes 7. Such an arrangement isillustrated in Figs. 6 and 7.

As shown in Fig. 6, connecting yoke 7 is provided with anarched section11 which has a center of curvature coinciding with the axis of theroller 12 of the two guide rollers. The arched portion 11 of connectingyoke 7Y carries the drawo creel 13 for a spool 14y with a large numberof yarn balls pivotably mounted thereon in the manner as customary intwo-cylinder spinning machines. In such a manner it is possible to swingeach time one of the draw-off creels located between two connectingyokes into the service aisle, which will considerably facilitate thehandling of the spools. Fig. 7 illustrates another possibility of movingthe draw-off creel 13 and spool 14 about the connecting yokes 7 whichare located laterally thereof. Thus, the same advantages may be attainedas with the previous embodiment.

In addition to the embodiments of the invention as described above,there is the further possibility of designing the arrangement accordingto the invention in still another manner by mounting mobile blowingunits, known as such, or any other suitablecleaning unit, or forexample, mobile air moistening units, so as to be movable along theconnecting yokes or along rails which are mounted between the individualcolumns 4- and extend in the longitudinal` direction of the machines.Each rail may then support one of the units referred to, or severalxtures or units may also travel thereon at short distances or greaterintervals from each other, depending upon the purpose to be attained.The manner in which the rail may extend above the machines isdiagrammatically shown in Figs. 8 to l0, which, however, illustrate onlya few examples of the many possibilities in which such a rail may bedesigned. For example, the arrangement of the connecting yokes 7according to Fig. 4 may yalso be designed so as to form a continuoustrack. This may be easily done by bending the individual con nectingyokes 7 at a slight angle at their ends so that the upper surfaces ofthose portions of the connecting yokes which are located between the twoends are disposed at the same horizontal level. If, in addition, rails15 are mounted on these surfaces in the manner as shown in Figs. ll and12, the insertion of curved portions 16 into the track rails of therespective connecting yokes 7 will form a continuous track, permittingan uninterrupted travel of the blowing unit or other apparatus. Thetrack for the blowing unit may thus be designed in accordance with therespective operating conditions, so that either at short or extendedintervals the same section of a machine may be reached and, for example,be cleaned from adhering dirt particles by means of the same blowingunit.

Obviously, the manner of mounting the connecting yokes is not restrictedto the presence of columns on the machines. In a similar manner, it ispossible to utilize frame or creel portions of the machines or othersupporting portions of the upper frame structure and to secure theconnecting yokes thereto in a similar manner as previously described.

Although my invention has been illustrated and described with referenceto the preferred embodiments thereof, I wish to have it understood thatit is in no way limited to the details of such embodiments, but iscapalble of numerous modifications within the scope of the appendedclaims.
